NXTCOLDTM is a self-contained industrial refrigeration system. It utilizes ammonia, a natural refrigerant and features an ultralow charge of less than one pound per TR (ton of refrigeration). NXTCOLD designed technology includes a U.S. patented refrigeration system controlled by measuring refrigerant quality within the evaporator. All systems contain state of the art industrial refrigeration components and are factory tested for performance. Temperature range is minus 60 F. (-51 C.) to plus 60 F. (16 C.). NXTCOLD units are engineered to improve performance and reduce energy consumption. For optimum performance, variable frequency drives (VFD) are used on compressors, evaporators and condenser fan motors. Power requirements are typically 10 to 15% less than traditional industrial refrigeration systems. NXTCOLD is expanding the use of self-contained packaged unit refrigeration systems for all industrial applications. NXTCOLD units are constructed for quick and easy roof top or ground level installation. Range is from 20 to 150 TR capacity.
